Can you list some machine learning use cases which interest you?

There are several reasons an interviewer will ask this type of question. The first is to understand your interests in machine learning and the type of topics you follow. The second is to see if your interests align with those of the organization and the type of work they do. This is important because organizations look for individuals with both talents and interests related to the job. Finally, as with most questions, the interviewer is looking to see how well you communicate your interests in simple, nontechnical language.
